Horticultural Classification Codes

Horticultural Classification Codes are often given to genera which have a large number of species or cultivars. They are used to categorise cultivated plants based on specific, shared characteristics such as shape, colour, size or flowering time, and can be displayed as letters or numbers

For example:
Dahlia ‘Sunset Kate (Sin) = Single flower
Rosa ‘Marigold’ (HT) = Hybrid Tea: Primrose group primulas are mainly grown as herbaceous perennials, and produce clusters of flowers on individual stems from the basal rosettes, although a few may also have umbel-like flowers. They are either spring-flowering, if grown without protection, or winter- to spring-flowering, if grown as biennial container plants in greenhouses or indoors.
